Pure dex bird vs pure dex bear.....preferred? Why?

[Superdexme]

I like the buff the bear has and the extra health over the bird..any comments?

Bear might have the additional buff of damage and more health, but the bird has more dodge and it has a vareity of skills which have a bigger range than that of the bear. It can root and use blast shot, blind etc from a distance. If the bear fails to beckon the bird in to use some of it's close range skills, the bird will definitely win.

as remixi said, dex bear is mostly a fail in pvp. he hasnt any ranged skills appart becon. and if the bird roots him or a mage freezes him, he cant even shoot and due to his low armor and dogde he will fall fast.

in pve i prefer dex bear bcz its more fun imo. i cant tank like a str bear but its ok with using a lot hp pots.

You should specify level and purpose (PvE or PvP) to get helpful answers.

For PvP, Dexbears are decent from 10-20 and also at 51-56. Dexbirds become useful 50+ in PvP, and also are at Endgame, tho they have been weakened for FFA purposes :/

For PvE, at lower levels the bear will propably be stronger due to the massive damage/crit boots of rage.
However, from 30 upwards birds will propably have a higher damage output and single target damage because of their ranged skills. Bears lack those, but they have some strong buffs and the ability to 'crow-control'. So you should consider tanking (which will be much easier in Str gear) and leaving the clearing part to mages/birds. When in a very strong (or potted) group you can always switch to Dexgear since a tank won't be needed. For soloing or damage dealing only (which isn't the main job of a bear IMO) Dex/Int is your best choice.
Some sets like the sentinel/custom talon sets are nicely balanced between tanking stats and damage dealing and do also offer range.
